All:
Regarding solar panel noise on HF; my neighbor's Solar Edge installation
generates high noise levels that effect 30 meters on up to VHF. I have a
couple of screenshots that show how the noise is generated during the
day, when the solar panels are illuminated by the sun and another that
shows how the noise disappears after sundown when the panels are no
longer energized.
I should mention that filed a complaint with Solar Edge in August of
2016 on the day of the installation. Over the course of 9 months, I
received numerous emails from them stating that they were working on a
solution. No action was taken until February, 2017 (7 months later) when
they attempted to fix the problem by changing out the Optimizers which
actually made things worse.
I finally contacted ARRL EMC engineer, Mike Gruber who then contacted
the manufacturer. Within a few weeks, I receive a phone call from the
CEO of Solar Edge who assured me that he would work with the ARRL to fix
the problem.
The plan is to install chokes and other RFI techniques similar to what
Tony Brock-Fisher outlined in his QST article. That has yet to take place.
My advise to those experiencing similar issues is to document everything
and contact the ARRL immediately. The more complaints that reach the
desks of solar manufactures, the better the chance they'll consider
improving their components.
